NASA’s James Webb Space Telescope has captured a lush, highly detailed landscape the iconic Pillars of Creation where new stars are forming within dense clouds of gas and dust. The three-dimensional pillars look like majestic rock formations but are far more permeable. These columns are made up of cool interstellar gas and dust that appear at times semi-transparent in near-infrared light.

Webb’s new view of the Pillars of Creation, which were first made famous when imaged by NASA’s Hubble Space Telescope in 1995, will help researchers revamp their models of star formation by identifying far more precise counts of newly formed stars, along with the quantities of gas and dust in the region. Over time, they will begin to build a clearer understanding of how stars form and burst out of these dusty clouds over millions of years.

Newly formed stars are the scene-stealers in this image from Webb’s Near-Infrared Camera (NIRCam). These are the bright red orbs that typically have diffraction spikes and lie outside one of the dusty pillars. When knots with sufficient mass form within the pillars of gas and dust, they begin to collapse under their own gravity, slowly heat up, and eventually form new stars.

What about those wavy lines that look like lava at the edges of some pillars? These are ejections from stars that are still forming within the gas and dust. Young stars periodically shoot out supersonic jets that collide with clouds of material, like these thick pillars. This sometimes also results in bow shocks, which can form wavy patterns like a boat does as it moves through water. The crimson glow comes from the energetic hydrogen molecules that result from jets and shocks. This is evident in the second and third pillars from the top — the NIRCam image is practically pulsing with their activity. These young stars are estimated to be only a few hundred thousand years old.

Although it may appear that near-infrared light has allowed Webb to “pierce through” the clouds to reveal great cosmic distances beyond the pillars, there are no galaxies in this view. Instead, a mix of translucent gas and dust known as the interstellar medium in the densest part of our Milky Way galaxy’s disk blocks our view of the deeper universe.

This scene was first imaged by Hubble in 1995 and revisited in 2014, but many other observatories have also stared deeply at this region. Each advanced instrument offers researchers new details about this region, which is practically overflowing with stars.

This tightly cropped image is set within the vast Eagle Nebula, which lies 6,500 light-years away.

The James Webb Space Telescope is the world’s premier space science observatory. Webb will solve mysteries in our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA.

Axiom 4 Mission Crew Settles Down at ISS, Begins Conducting Research

Axiom 4 mission’s crewmates began conducting biomedical research aboard the International Space Station on Tuesday. Expedition 73 and Ax-4 crews found electrical muscle stimulation and cellular immunity. The Cargo transfers and exercise gear maintenance take a day for orbital residents.

Takuya Onishi, Situation Commander from JAXA( Japan Aerospace Exploration Agency), has begun the shift in continuation of his space biology studies. His blood and saliva samples are being collected for storage and processing. Further, he spun the specimens in a centrifuge and placed the blood samples in the freezer. After that, he stowed the samples in the incubator.

JAXA’s Takuya Onishi Leads Cellular Immunity Study with Blood and Saliva Analysis

According to a report from NASA, the samples will be analysed to determine the effect of microgravity on cellular immunity, observe stress-related immune reactions, and learn about how to treat symptoms of immunity. The flight engineers Johnny Kim, Anne McClain, and Nichole Ayers spent their day on orbital lab maintenance and further support activities of the crew. Kim focused mainly on orbital plumbing as he replaced and drained the Tranquillity module.

Ayers checked cables and power components in the Destiny laboratory module and deactivated and placed the microscope. McClain took the cognition test on the laptop and kept on supporting the Ax-4 crew at a time of a busy schedule.

Ax-4 Crew Explores Muscle Stimulation and Space Suit Fabric Efficiency in Microgravity

Veteran astronaut Peggy Whitson and her Ax-4 crewmates Shubhanshu Shukla, Tibor Kapu and Uznański-Wiśniewski conducted numerous space investigations throughout the lab. The private scientists in their second full week on the station found out that the electrical muscle simulation escalates the space-related and muscle atrophy in space. Ax-4’s other experiments looked at suit fabrics promote thermal comfort with exercising the weightlessness, crew health and agriculture in space.

Sergey Ryzhikov and Alexey Zubritskiy worked together on the Zvezda service module, repairing and organising components on a treadmill, one of the two inside the space station, which included the COLBERT treadmill. Kirill Peskov started his day by going through the biological samples from the crewmates. At the end of his shift, he transfers water from Progress 92 cargo craft and unloads the stuffs of hardware and crew supplies.

Astronomers Discover 3I/ATLAS, Largest Interstellar Comet Yet Detected

Astronomers Discover 3I/ATLAS, Largest Interstellar Comet Yet Detected

Astronomers have discovered the third interstellar comet to pass through our solar system. Named 3I/ATLAS (initially A11pl3Z), it was first spotted July 1 by the ATLAS telescope in Chile and confirmed the same day. Pre-discovery images show it in the sky as far back as mid-June. The object is racing toward the inner system at roughly 150,000 miles per hour on a near-straight trajectory, too fast for the Sun to capture. Estimates suggest its nucleus may be 10–20 km across. Now inside Jupiter’s orbit, 3I/ATLAS will swing closest to the Sun in October and should remain observable into late 2025.

Discovery and Classification

According to NASA, in early July the ATLAS survey telescope in Chile spotted a faint moving object first called A11pl3Z, and the IAU’s Minor Planet Center confirmed the next day that it was an interstellar visitor. The object was officially named 3I/ATLAS and noted as likely the largest interstellar body yet detected. At first it appeared to be an ordinary near-Earth asteroid, but precise orbit measurements showed it speeding at ~150,000 mph – far too fast for the Sun to capture. Astronomers estimate 3I/ATLAS spans roughly 10–20 km across. Signs of cometary activity – a faint coma and short tail – have emerged, earning it the additional comet designation C/2025 N1 (ATLAS).

Studying a Pristine Comet

3I/ATLAS was spotted well before its closest approach, giving astronomers time to prepare detailed observations. It will pass within about 1.4 AU of the Sun in late October. Importantly, researchers can study it while it is still a pristine frozen relic before solar heating alters it. As Pamela Gay notes, discovering the object on its inbound leg leaves “ample time” to analyze its trajectory. Astronomers are now racing to obtain spectra and images – as Chris Lintott warns, the comet will be “baked” by sunlight as it nears perihelion.

Determining its composition and activity is considered “a rare chance” to learn how planets form in other star systems. With new facilities like the Vera C. Rubin Observatory coming online, researchers expect more such visitors in the years ahead. 3I/ATLAS offers a rare chance to study material from another star system.

NASA's New Horizons Proves Deep-Space Navigation via Stellar Parallax

NASA’s New Horizons spacecraft carried out an unprecedented deep-space star navigation test while 438 million miles from Earth. Using its long-range camera in April 2020, it captured images of Proxima Centauri and Wolf 359, which appeared slightly shifted in the sky compared to Earth’s view – a striking demonstration of stellar parallax. It was the first-ever demonstration of deep-space stellar navigation. By comparing these images to Earth-based observations and a 3D star chart, scientists calculated New Horizons’ position to within about 4.1 million miles, only about 26 inches across the United States.

Stellar Parallax Test

According to the paper describing the results, accepted for publication in The Astronomical Journal, New Horizons’ camera imaged Proxima Centauri (4.2 light-years away) and Wolf 359 (7.86 light-years) on April 23, 2020. From the spacecraft’s distant vantage point, the two stars appear in different positions than seen from Earth – the essence of stellar parallax. By comparing those images with Earth-based data and a three-dimensional map of nearby stars, the team worked out the probe’s location to within about 4.1 million miles.

As lead author Tod Lauer explained, “Taking simultaneous Earth/Spacecraft images we hoped would make the concept of stellar parallaxes instantly and vividly clear”. He added, “It’s one thing to know something, but another to say ‘Hey, look! This really works!’”.

New Horizons and Future Missions

New Horizons, the fifth spacecraft to leave Earth and reach interstellar space, flew past Pluto and its moon Charon in 2015, sending home the first close-up images of those distant icy worlds. Now on an extended mission, the probe is studying the heliosphere.

New Horizons’ principal investigator Alan Stern called the parallax test “a pioneering interstellar navigation demonstration” that shows a spacecraft can use onboard cameras “to find its way among the stars”, in a statement. He also noted it “could be highly useful for future deep space missions in the far reaches of the Solar System and in interstellar space”
